    For ease of use, we are including the React, ReactDOM and Babel CDN
    builds to make getting started as fast as possible.
    
    In production, you'll want to instead look at using something 
    like Gulp, Grunt or WebPack (my personal recommendation) 
    to compile JSX into JavaScript. Also, check out:
